Table View not Updating after adding a new Row

Hey Folks !

Hope you all are doing well.

I have been through a lot of similar links regarding the question but yet i didn't found any perfect solution regarding that. Here's my code :

Code:

---

// Called this in constructor
model = new QStandardItemModel(0,0,this);
 
// this is the logic of showing the view for Table View
tableView = new QTableView(this);
    tableView->setModel(model);
    tableView->verticalHeader()->setVisible(false);
    tableView->verticalHeader()->setDefaultSectionSize(10);
 
    for(int i = 0; i < clusterNames.length(); i++) {
        QStandardItem *clusterName_i = new QStandardItem(clusterNames[i]);
        QStandardItem *clusterIP_i = new QStandardItem(clusterIPs[i]);
 
        model->setItem(i, 0, clusterName_i);
        model->setItem(i, 1, clusterIP_i);
    }
 
    tableView->viewport()->update();

---

Logic/Explanation : The logic which i am doing behind this functionality as i populate a QDialog on a button and the data which i insert on the opened Dialog which is of different class. After adding the values i close that dialog and noticed that Tree & Table View aren't updating automatically but when i close that window and reopened it i saw it with updated values.

If anyone have suggestions or the solution that would be a great help for me.

Thanks In Advance

The view should update automatically if the model changes.

Maybe check if you are updating a different model than the one you are showing.
